Mr. Ohlig:
I am not referring exactly to a physical film as technology has been
made public regarding liquid crystalline light valves (thermally
written) and liquid crystalline drawing devices that "act" as reuseable
films.
Perhaps I was not clear.
Two companies, which I do not have any ties to, have US patents:
Asahi Kogaku Kogyo Kabushki Kaisha, Tokyo, Japan
patents 5,026,145; 5,062,692; and 5,078,474 (1988-1990)
Omnichrome, CA
patent 5,556,884 (1995)
The abstracts are available at http://patents.uspto.gov/index.html
I have no additional information but am interested in anyone who has
purchased devices or licensed similar technology.
I hope this is of use.
Sincerely,
Dieter
Herr Dieter Miese
